DISINFECTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 748,413, dated December29, 1903.

Application led September 12,1908. Serial No. 172,915. (No model.)

To a/ZZ whom it may concern:

Beit known that I, FREDERICK C. NYE, of Syracuse, in the county ofOnondaga, in the State of New York,'have invented new and usefulImprovements in Disinfecting Appal ratus,of which the following, takenin connection with the accompanying drawings, is a full, clear, andexact description.

This invention relates to improvements in disinfecting apparatus whichis adapted to be placed in the toilet-room or other locality whereoifensive odors or disease germs are liable to accumulate.

The primary object of this invention is to inclose a liquid disinfectantor other vaporizing material and also a liquid or other vaporizingperfume in such manner as to permit the vapor to escape into the room.

Other objects will appear in the subsequent description. i d

In the drawings, Figure 1 is a longitudinal vertical sectional view ofmy improved disinfectiug apparatus. Figs. 2 and 3 are transversesectional views taken, respectively, on lines 2 2 and 3 3 of Fig. 1.

Similar reference characters indicate corresponding parts in all theviews.

In carrying outthe objects of this invention I provide an upright tank 1with a horizontal partition 2, which divides the tank into up-v per andlower chambers 3 and 4, the upper chamber 3 being of greater capacitythan the lower chamber4 and contains a liquid disinfectant 5. This tankmay be of any desired form, size, or construction and is usually securedto one of the side walls of a room upon brackets 6.

The partition-Wall 2 is provided with one or more upright vapor pipes orfiues 7, having their lower ends communicating with the subchamber 4,and their upper ends communicate with the interior of the chamber 3 atpoints above the level of the liquid 5 through ,the medium of lateraltubular offsets 8,havin g openings in theirsidesimmediately above theliquid-level, so that the disinfectant vapor of the liquid 5 escapes orpasses upwardly into thetubes 8 and then downwardly through the pipes oriiues 7 into the subchamber 4.

The subchamber 4 is provided with a bottom wall 9, having a series ofperforations 10 where the vaporized disinfectant passes into the room inwhich the apparatus is located for the purpose of deodorizing ordisinfecting the vitiated air in said room. It is evident, however, thatone or more of these pipes or vapor-fines may be provided with an upturnedextremity leading from the interior of the chamber 3, and I havetherefore shown such a pipe or flue 11 having a lateral offset `with anopening in its upper end or side and above theliquid-level; but thevaporized disinfectant escapesA 'in the same manner as through the pipes7 into the snbchamber 4. This chamber 4 serves merely as a reservoir forthe vapor which escapes from the chamber 3 and holds such vapor inreserve, which gradually and continuously discharges through theapertures 10 into the room.

The chamber 3 is normally hermetically sealed except as it communicateswith the atmosphere through the medium ofthe pipes 7 and 11, chamber 4,and apertures 10, so as to prevent undue evaporation of the disinfectingliquid, and I therefore provide the chamber 3 with an upper wall 12,which in this instance is removable to permit the interior of thechamber to be thoroughly cleansed when desired, said `upper wall beingsecured to the frame of the tank by suitable fastening means, as screws13.

It is necessary to replenish or refill the reservoir 3 when the previoussupply is exhausted or becomes ineective, and I therefore provide thetop wall with an inlet-passage 14, which communicates with the interiorofthe ,chamber 3, and its outer end is normally closed by a removablecap l5 to prevent undue evaporation and also to prevent the entrance ofany dust or foreign matter. It is also necessary to make some provisionfor the cleansing of the chamber 3 and to permit the residue or liquidto be drawn oif when desired,

land I therefore provide an outlet-conduit 16,

having one end secured to the Wall 2 aud communicating with the interiorofthe chamber 3 and its other end extended outwardly through one of theside walls of the chamber 4to the atmosphere and provided with a valve17, which is normally closed when the apparatus is in operation, but maybe opened to draw o the contents of the chamber 3.

The means for introducing the vapor perfume into the room consists of avertical IOO stand-pipe 18, which extends through the chamber 3, aboveand beneath the top wall 12 and downwardlyl through the horizontalpartition 2, and contains a liquid perfume, the lower end beingcontinued into the cham- -ber 4 and laterally through the adjacent endWall of the tank and is provided with a normally closed valve 20,which-may be open when desired to draw off the liquid contents of thestand-pipe 18. The upper portion of this stand-pipe within the chamber 3is provided with a lateral offset 21, extending through the end Wall ofthe chamber 3, and its outer end is provided with a valve 22,which isnormally open to permit the escape of the vapor perfume into the room inwhich the apparatus is located, it being understood that the lateraloffset 21 is disposed in a plane above the level of the liquid perfume.In order that this latter vapor efect may be more permanent andeffective, I introduce a wick 23 into the open end of the stand-pipe, sothat its lower end extends into the liquid while its upper portionextends across the inlet of the offset 2l, the upper open end of thestandpipe being normally closed by a removable cap 24 to prevent undueevaporation of Ithe liquid perfume and at the same time to permit thestand-pipe to be refilled when desired.

In brief, the operation of this invention is as follows: The liquiddisinfectant is first introduced into the chamber 3 through the inlet 14until it reaches a level beneath the mouths of the vapor-tubes 7 and l1,after which the inlet 14 is closed by caps 15. The liquid perfume andwicks 28 are introduced into the stand-pipe 18 either before or afterthe disinfecting liquid is introduced into the chamber 3, after whichthe cap 24 is placed in operative position, it being understood thatduring these illing operations the Valves 17 and 20 are closed and thatin the operation the valve 22 is open. The apparatus is now ready foroperation, during which the liquid disinfectant is vaporized and passesoutwardly through the conduits 7 and l1 into the chamber/i and thenceinto the room through the apertures 10 in the bottom wall 9, and theliquid perfume is simultaneously vaporized and passes outwardly into theroom through the outlet 2l and valve 22.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. A disinfecting apparatus comprising a tank having a horizontalpartition dividing the interior of the tank into upper and lowerchambers, the upper chamber containing the disinfecting liquid, aconduit leading from the upper chamber above the liquid-level to thelower chamber, said lower chamber communicating with the atmosphere, anda discharge-conduit leading from the bottom of the upper chamber to theoutside of the tank and provided with a valve for controlling thedischarge of the liquid.

2. A disinfecting apparatus comprising a tank having a horizontalpartition dividing the interior of the tank into upper and lowerchambers, the upper chamber containing a disinfecting liquid, a conduitleading from the upper chamber above the liquid-level to the lowerchamber, said lower chamber communicating with the atmosphere, conduitsleading to and from the interior of the upper chamber for permitting thelling and discharging of the liquid therethrough and therefrom andseparate means for closing said conduits.

3. An apparatus of the class described cornprisiug a tank having ahorizontal partition .dividing the interior of the tank into upper andlower chambers, the upper chamber con- Vtaining a liquid disinfectant, avapor-pipe rising from the partition and having its upper endcommunicating with the interior of the upper chamber above theliquid-leveland its lower end communicating with the interior of thelower chamber, said lower chamber communicating with the atmosphere, incombination with a stand-pipe containing a liquid perfume and extendingthrough the upper and lower walls of the upper chamber and provided withmeans for controlling the escape of the vapor to atmosphere.

4. An apparatus of the class described comprising a tank having ahorizontal partition dividing the interior of the tank into upper andlower chambers, the upper chamber containing a liquid disinfectant andthe lower chamber communicating with the atmosphere, pipes connectingthe interior of the upper chamber above the liquid-level with theinterior of the lower chamber, a valveconduit leading from theliquid-chamber to the outside of the tank, a stand-pipe containing aperfume and opening to atmosphere and an absorbent in the stand-pipe.

In witness whereof I have hereunto set my hand on this 3d day ofSeptember, 1903.
